Abstinence

I was at the Nellis Air Force base with my family doing some grocery shopping. We entered through the food court and I all of a sudden got hungry. My aunt told me to buy something but I told her I can't eat fast food till Easter. And she said, "oh yea you're practicing abstinence." When she said that I thought she meant I'm practicing sexual abstinence. So I said, "oh no I'm not doing that, I gave up fast food."
